The state of the atmosphere at a specific time and place.
What is weather?
100
Classification by shape and height; stratus, cumulus, cirrus; etc.
What is cloud classification?
100
When cloud droplets combine and grow large enough to fall to earth. The form around small particles, such as salt and dust.
What is precipitation?
100
A large body of air that has properties similar to the part of the earth's surface over which it develops.
What is an air mass?
100
These occur in warm, moist air masses and along fronts - the warm air is forced upwards and cools and forms condensation.
What is a thunderstorm?
200
The measure of the average amount of motion of molecules. Here, in the air.
What is the air temperature?
200
Warm air is being forced upward, it expands, and it cools - relative humidity reaches 100% and water vapor condenses into tiny droplets are particles like dust and salt.
What is cloud formation?
200
The determining factor in whether precipitation forms as rain, snow, sleet, or hail.
What is air temperature?
200
With weather patterns, wind is blowing AWAY from this location.
What is a center of high pressure?
200
Warm air lifts rapidly inside a storm cloud as cooler air sinks. This causes opposite parts of a cloud to become oppositely charged, and ______ occurs.
What is thunder and lightning?
300
The result of air moving from high pressure to regions of low pressure.
What is wind?
300
Latin for "dark rain cloud". The term for clouds that are associated with rain or snow.
What is nimbus?
300
The precipitation that forms when rain droplets pass through a layer of freezing air near the Earth's surface.
What is sleet?
300
A boundary between two air masses of different density, moisture, or temperature; cloudiness, precipitation, and storms sometimes occur here. There are four types.
What is a front - cold, warm, occluded, and stationary.
300
These can be produced by some of the most severe thunderstorms - it is a violently rotating column of air, that stays in contact with the ground.
What is a tornado?
400
The effect of cooler air being denser and tending to sink.
What is atmospheric pressure?
400
Prefixes used for clouds to describe the height of the cloud base.
What is cirro-, alto-, and strato-.
BONUS: What are the heights associated with each of the prefixes?
400
This type of precipitation forms in the cumulonimbus clouds of a thunderstorm when water freezes around a nucleus of ice.
What is hail?
400
This involves three air masses of different temperatures. - colder air, cool air, and warm air.
What is an occluded front?
400
This is a large, swirling, low pressure system that forms over the warm Atlantic Ocean.
What is a hurricane?
500
The temperature at which air is saturated with water and condensation forms.
What is the dew point?
500
A layered cloud that can bring long, steady rain or snowfall.
What is a nimbostratus cloud?
500
This depends on several factors, including the strength of the updrafts in a cloud.
What is the size of raindrops?
500
These are shown on the map with red semi-circles and blue triangles.
What is a stationary front?
500
In cold temperature, if winds reach 56 km/h and the temperature is low and the visibility is less than 400 m then a storm is classified as a ______.
